For HTML output, `racketblock' and `codeblock' now use a style that
discourages line wrapping. So, when you make code that is too wide, it
will usually[*] extend past the right margin instead of wrapping lines.
This doesn't mean that too-wide code is ok; it's just a better failure
mode in most cases.
[*] Probably not for IE7 and earlier.
Latex output changed in more ways:
* Documentation via `defform', `defproc', etc., renders with a
vertical bar to the left, instead of a thin horizontal line above.
(Thanks to an anonymous DLS'11 reviewer for this suggestion.)
Also, those forms add vertical space like `codeblock', so they look
right in document formats such as the SIGPLAN style.
* Table content is vertically centered by default, making it more
consistent with HTML.
* In a table cell, a paragraph with a `#f' style name is rendered as a
single line (as before), but a width is imposed on paragraphs that
have a style name to make them flow as paragraphs.
* More generally, a paragraph or nested flow can be "boxable", which
means that it supplies a rendering mode (via a `box-mode' style
property) such that the output is a Tex box instead of a paragraph.
Box mode is triggered by cells in a multi-column table.
The output from `racketblock' and `codeblock' is boxable, which
means that tables and table columns containing code automatically
size the expected way (i.e., like HTML). Meanwhile, outside of a
table, boxable blocks render the old way, which allows page breaks
within the block and generally cooperates better with Latex document
styles.
